FUMPING APPARATUS.

Application filed March 8, 1924. Serial No. 697,775.

To all whom t may conce/rn.:

Be it known that l. Animar lil. Him.. a citizen of the United Statesq residing at Arkansas City, in thc county of Cowley and -State of Kansas` have invented certain new Other objects of the invention will ap.

pear upon consideration of the following detailed description and accompanying drawings, in which:

The figure 1s a longitudinal section through the pump constructed in accordance with my invention.

Referring to the drawing` by numerals, the discharge chute 1 leads from the tank 2 vandthe contents of the tank are passed through the chute and into the lower end thereof. The lower end of the chute is connected to one end of the intake cylinder l and the entrance to the cylinder is pro-- vided with clapper valve 5 hingedly mounted, adapted to open when the piston 6 is thrown inwardly. The piston 6 .is adapted to reciprocate in the intake cylinder t and is provided with a central tapered opening 'r' which is in communication with the open end of the hollow piston rod 8 kwhich passes through the-closed end 9 of the cylinder which is provided with a suitable stuffing box as shown.

ln longitudinal alignment with the intake cylinder L1 is the discharge cylinder' 10, which is spaced apart from the intake cylinder and has its closed end 11 provided with a suitable stutling boX through which the hollow piston rod 8 is extended. The discharge cylinder 11 is provided with a piston 12 connected to the end of the piston rod 8 and the open end of the hollow piston rod is provided with a clapper valve 13. The discharge cylinder 10 is provided with a discharge spout 14 through which the contents of the cylinder are ejected when the device is in operation.

A steam supply pipe 15 leading from a suitable source of steam supply is connected to the steam line 16 which is provided with connections 17 and 18 leading` to the cylinto open and close the valves.

ders -lainl l() respcctively. Each of the connections 1T and 18 is provided with a valve 19 and these valves are equipped with opcratirng` levers whichn when actuated, serve The valves 19 are of the usual three way type and when the valve members are moved to one position they permit the steam pressure to enter theJ cylinders and when moved to another position permit the pressure to exhaust from the cylinder lin a usual manner. A connecting rod 21 has its ends ioined to the operating' levers 2() of the valve and thc connecting rod is equipped, intermediate its ends3 with the yolre member 22 adapted to engage one end of a ylever 23 pivoted on the support 2li. The lever 23 has its opposite end connected to fixed sleeve 12 on the central portion of the hollow shaft 8 so that moven'ient is imparted to the lever 23 when the hollow piston rod 8 is reciprocated.

Then the apparatus is in use, the material will be received through the chute 1 and the inward movement of the piston 6 in the intake cylinder l will draw the material into the intake cylinder, the valve 5 automatically opening. This movement of the hollow piston rod causes the lever 23 to impart motion to the connecting rod 22 which opens the valve 19 in the connection 17 and closes the valve in the connection 18. `Thus the steam is introduced into thedischarge cylinder 4 behind the piston 6 and imparts opposite motion thereto closing the valve 5 and forcing the materials through the conical shaped opening 7 into the hollow piston rod 8. The material passes through the pisa ton rod into the discharge cylinder 10; as the clapper valve 13 opens the piston 12 is withdrawn into the discharge cylinder 10. This motion of the hollow piston rod imparts opposite motion to the connecting rod 21, thus reversing the positions of the valves 19 and introducing steam into the discharge cylinder 10 behind the piston 12 causing the ice i W'hat l claim is: A pumping apparatus comprising an intake chute, an intake cylinder connected to the chute, clapper valves between the intake chute and the end of the cylinder, an intake piston mounted in the said intake cylinder and provided with a central conical opening, a hollow piston rod extending through the closed end of the intake cylinder and in open communication with the sai'd opening in the intake piston, a discharge cylinder` the said hollow piston rod being eX- tended through the closed end oie the discharge cylinder, a discharge piston in the TH" said discharge cylinder connected to the end of said hollow piston Valve, a clapper rod carried by the said discharge piston and arranged to open and close the open end of the said hollow piston rod, a steam line, steam Valves in the said steam line, a connecting rod connecting 4the said steam valves, a yoke on the said connecting rod, and a lever connected to the said hollow piston rod and engageable with the said yoke to impart motion to the said Valves' When the said piston rod is actuated.

In testimony whereof, I have aiiixed my signature.
